Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton shanks
- Provide meat and collagen that give the broth body and richness as they cook.
- Onion
- Adds savory sweetness and aromatic flavor to the broth as it simmers.
- Bread crust
- Can help clarify and mellow the broth's flavor during long cooking.
The step that matters
Remove the fat from the top when cold before serving.. Fat rises to the surface and solidifies as the soup cools, so skimming it when cold removes most of the greasiness and leaves a cleaner-tasting broth.
Swap the onion
How well each one fits the dish's main ingredients (mutton, pepper, bread):
- Capsicumfits better
- Tomatofits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against mutton, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
